How to implement UnboundedSender<Response>?

[ghost]

#[derive(NetworkBehaviour)]
#[behaviour(out_event = "MyEvent")]
struct MyBehaviour {
    gossipsub: gossipsub::Behaviour,
    mdns: mdns::async_io::Behaviour,
    response_sender: UnboundedSender<Response>,
}

enum MyEvent {
    GossipsubEvent(gossipsub::Event),
    MdnsEvent(mdns::Event)
}

impl From<gossipsub::Event> for MyEvent {
    fn from(event: gossipsub::Event) -> Self {
        Self::GossipsubEvent(event)
    }
}

impl From<mdns::Event> for MyEvent {
    fn from(event: mdns::Event) -> Self {
        Self::MdnsEvent(event)
    }
}

error[E0277]: the trait bound `MyEvent: From<<tokio::sync::mpsc::UnboundedSender<Response> as NetworkBehaviour>::OutEvent>` is not satisfied

   |          ^^^^^^^^^^^^^^^^ the trait `From<<tokio::sync::mpsc::UnboundedSender<Response> as NetworkBehaviour>::OutEvent>` is not implemented for `MyEvent`
   |
   = help: the following other types implement trait `From<T>`:
             <MyEvent as From<libp2p::libp2p_gossipsub::Event>>
             <MyEvent as From<libp2p::libp2p_mdns::Event>>
   = help: see issue #48214
   = note: this error originates in the derive macro `NetworkBehaviour` (in Nightly builds, run with -Z macro-backtrace for more info)

Later, i could use #[behaviour(ignore)].

You should not have a Sender in your behaviour struct but instead handle the events from Swarm via the next().await function.

Have you seen the file-sharing example?

Let me know if that makes things clearer :)
